In this last of the 14 Rathbone-Bruce films, the legendary Holmes must apply his keen ear for music to solve a baffling case involving a trio of cheap music boxes made in Dartmoor Prison that contain the secrets to vast riches. The three boxes are auctioned off for pocket change, but a group of criminals show that they are willing to kill the purchasers for them. When the first of these victims is Watson’s school chum Gilbert “Stinky” Emery (Edmond Breon), Holmes is on the case. This 1946 film, also released under the title of Dressed to Kill, is loosely based on Arthur Conan Doyle's A Scandal in Bohemia.

Between 1939 and 1945, Universal Pictures filmed 14 Sherlock Holmes mysteries starring Basil Rathbone as Arthur Conan Doyle's legendary detective and Nigel Bruce as Dr. Watson. All but two of the films were "updated" to World War II England and often included Axis spies or saboteurs as antagonists. Each movie has been lovingly restored by the UCLA Theatre Archives from 35 mm master copies into a digital format and may be viewed in either colorized versions or in the original black and white.
